Note 2: Temperature coefficient is determined by the box method in which the maximum change over the temperature range is

divided by

∆T.

Note 3: Gain error is measured at the full-scale code and is calculated with respect to the reference voltage (REF).

Note 4: Resistor tolerance is typically ±20%.

Note 5: Guaranteed by design, not production tested.

Note 6: Noise is measured at the reference output.

Note 7: Min/max range guaranteed by gain-error test. Operation outside min/max limits results in degraded performance.
